BackgroundRadical resection is an effective therapeutic method to increase the survival rate of patients with gallbladder cancer (GBC). In addition to the surgical approach, the relationships between various clinicopathologic factors and the outcome of patients with GBC remain controversial.MethodsClinical and laboratory examination characteristics, pathological and surgical data, and post-operative survival time of 338 patients with advanced GBC who received treatment at the First Affiliated Hospital of Xi'an Jiaotong University, China from January 2008 to December 2012 were analyzed retrospectively. Factors influencing the prognosis of GBC after surgery were analyzed by univariate and multivariate analysis.ResultsThe overall survival rates for curative resection patients were significantly greater than those for non-curative resection patients (1-,3-,5-year survival rate and mean-survival time: 59.0%, 47.3%, 44.3% and 22.0 months vs. 12.7%, 8.3%, 7.7% and 3.0 months) (P < 0.001). For the curative resection patients, positive margin, lymph node metastasis, poorly pathological differentiation and the presence of ascites were all independent risk factors for poor prognosis. For patients with T3 stage, neither segmentectomy of IVb and V nor common bile duct resection improved the prognosis (P = 0.867 and P = 0.948). For patients with T4 stage, aggressive curative resection improved the prognosis (P = 0.007).ConclusionsAn advanced T stage does not preclude curative resection. Positive margin, lymph node metastasis, poorly pathological differentiation and the presence of ascites are all independent risk factors for poor prognosis in the curative intent resection patients. The range of liver resection and whether common bile duct resection is performed do not influence the prognosis as long as R0 resection is achieved.
This study provides evidence, for the first time, that the PPAR-gamma agonist rosiglitazone significantly reduces endotoxin-induced acute lung injury in rats.
Patients with gallbladder ASC-SCC were similar to those with AC in clinical characteristics, but tended to have more infiltration of multiple adjacent organs and lymphatic metastasis. Curative resection could give these patients better outcomes.
Islet transplantation for the treatment of autoimmune diabetes is more difficult because of the additional barrier presented by the autoimmunity. We tested the ability of hamster anti-rat CD154 to prevent recurrence of diabetes in renal subcapsular islet isografts in DR-BB (RT1uu) rats with established autoimmune diabetes. Experimental animals with established diabetes received intravenous injections of 15 mg/kg anti-CD154 on a specified schedule starting 2 days before renal subcapsular transplantation of an islet isograft. Control animals received either saline or hamster IgG. Plasma glucose levels >250 mg/dl over 3 days were used to indicate the recurrence of diabetes. Rats that received saline (n = 5) or control antibody (n = 3) had a recurrence of diabetes 6-11 days after transplantation. Histological examination of islet isografts from these rats showed complete destruction of the insulin-producing portion of the isograft with residual cells positive for glucagon. Recipient rats that received anti-CD154 at the 15-mg/kg dosage (n = 6) did not have a recurrence of diabetes for 308-461 days after transplantation. Islet isografts removed from the rats showed low levels of insulin immunoreactivity, high levels of insulin mRNA, and focal infiltration with lymphocytes but no evidence of islet destruction. Mean peak antibody concentration was 266 µg/ml and returned to undetectable levels by 67-88 days after transplantation. Rats that received anti-CD154 starting at 4-7 days after transplantation had a recurrence of diabetes within 11 days of the isotransplantation. Therefore, anti-CD154 as the sole immunomodulator prevented the recurrence of diabetes in islet isografts in rats with established autoimmune diabetes. This suggests that CD40/CD154 blockade is effective in preventing the insulitis or the effector phase of autoimmune diabetes. Diabetes 49:1666-1670, 2000 A utoimmune diabetes in animal models and humans results from the development of autoreactive T-cells that are targeted to destroy the -cells, which results in the insulitis characteristic of type 1 diabetes. Therefore, the initiation of the loss of self-tolerance and the effect of the loss of tolerance in autoimmune diabetes both appear to be T-cell dependent (1,2). Even though the exact mechanism for the development of autoreactive T-cells is unclear, the initiation of the autoimmune response probably involves interaction between the major histocompatibility complex (MHC) protein of anti- gen-presenting cells (APCs) and the T-cell receptor on T-cells. In addition to the MHC-T-cell receptor interaction, other receptor-ligand interactions between APCs and T-cells are important in determining the outcome of the APC-T-cell interaction. The interaction of CD40 on APCs and of CD154 on T-cells represents one of the important costimulatory pathways (3-6).Regarding the insulitis of autoimmune diabetes, the CD40/CD154 costimulatory pathway may also be important at the effector phase of the autoimmune response through interactions between CD154 + T-cells and CD4...
ObjectiveTo analyze the clinical epidemiological characteristics of patients with gallbladder carcinoma recruited from 17 hospitals in five northwestern provinces of China (Shaanxi Province, Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region, and Xinjiang Uygur Autonomous Region) from 2009 to 2013, and to summarize the clinical diagnosis and treatment data of gallbladder carcinoma.MethodsClinical information of 2379 patients with gallbladder carcinoma from 17 hospitals in five northwestern provinces of China was retrospectively collected and analyzed using the “Questionnaire for Gallbladder Carcinoma Patients in Northwestern Area of China.” All information was verified with EpiData software and analyzed with SPSS 13.0 software.Results(1) Gallbladder carcinoma accounted for 2.7% (2379/86,609) of all biliary tract diseases during the study period, which was significantly higher than that from 1986 to 1998 (P < 0.001). (2) Gallbladder carcinoma was more prone to occur in elderly women. The male:female incidence ratio was 1.0:2.1, the average age of onset of disease was 63.7 ± 11.3 years, and the incidence was higher in farmers than in other occupational groups. (3) A total of 57.2% (1360/2379) of patients with gallbladder carcinoma also had gallstones. (4) Abdominal pain (1796/2379, 75.5%) and jaundice (727/2379, 30.6%) were the most common clinical manifestations, 81.2% (1527/1881) were positive in those receiving B ultrasound examinations and 90.7% (1567/1727) were positive in those undergoing computed tomography, and 64.5% (1124/1742) of patients with gallbladder carcinoma were positive for carbohydrate antigen (CA) 19-9. (5) The pathological type of gallbladder carcinoma was mainly moderately and poorly differentiated adenocarcinoma with a high degree of malignancy. At admission, 55.1% (1091/1981) of patients had stage IV cancer among patients with TNM staging information; 55.9% (1331/2379) had lymphatic metastasis, 29.7% (706/2379) had bile duct metastasis, and 53.1% (1263/2379) had liver metastasis. (6) A total of 283 patients (283/2379, 11.9%) had incidentally detected gallbladder carcinoma. (7) The rate of radical surgical resection was 30.4% (723/2379).ConclusionThe proportion of gallbladder carcinoma in biliary tract diseases in the northwestern area of China was significantly higher from 2009 to 2013 than from 1986 to 1998. Gallbladder carcinoma was common in older women and mainly diagnosed at an advanced stage. Compared with other surveys in different regions, the rate of metastasis in this survey was high, leading to a low resection rate. Populations at high risk should undergo B-ultrasound examinations at regular follow-up intervals to increase the rate of early diagnosis of gallbladder carcinoma.
Objectives: To evaluate the outcomes of clinical pharmacist-led medication therapy management (MTM) services for patients with chronic obstructive pulmonary disease (COPD). Methods: Two hundred COPD patients admitted by the Department of Respiratory and Critical Care Medicine of Baoding No.1 Central Hospital during January 2019 and December 2020 were randomly assigned to a control group (n =100) and an experimental group (n =100). Patients in the control group received conventional treatment, while those in the experimental group were provided with MTM services based on the conventional treatment for comparative analysis of outcome measures, including use of antibacterials during hospital stay, length of stay (LoS), costs of hospitalization (CoH), cases of adverse drug reactions (ADRs), and medication adherence (MA) and COPD assessment test (CAT) score one and six months after discharge. Results: Compared with the control group, the experimental group had reduced use of antibacterials during hospital stay, LoS, CoH, and ADR rate (P <0.05). After discharge, patients in both groups showed remarkable improvements in MA and CAT scores in comparison with their performances upon admission, and the experimental group exhibited better MA and higher CAT score than the control group, with the differences indicating statistical significance (P <0.05). Conclusion: MTM designed for COPD patients can improve pharmacist-led service quality and clinical outcomes of COPD. doi: https://doi.org/10.12669/pjms.37.7.4518 How to cite this:Liu M, Liu J, Geng Z, Bai S.

The factors underlying prognosis for gallbladder cancer (GBC) remain unclear. This study combines the Bayesian network (BN) with importance measures to identify the key factors that influence GBC patient survival time. A dataset of 366 patients who underwent surgical treatment for GBC was employed to establish and test a BN model using BayesiaLab software. A tree-augmented naïve Bayes method was also used to mine relationships between factors. Composite importance measures were applied to rank the influence of factors on survival time. The accuracy of BN model was 81.15%. For patients with long survival time (>6 months), the true-positive rate of the model was 77.78% and the false-positive rate was 15.25%. According to the built BN model, the sex, age, and pathological type were independent factors for survival of GBC patients. The N stage, liver infiltration, T stage, M stage, and surgical type were dependent variables for survival time prediction. Surgical type and TNM stages were identified as the most significant factors for the prognosis of GBC based on the analysis results of importance measures.
